DEVICE FOR INPUT

A utility model relates to the design of keyboard input devices, such as a keyboard, that can be used for computers, laptops, typewriters, and other similar devices.

Used at the present; her time input devices, such as a computer keyboard or typewriter, use the specific distance between the keys and the arrangement of characters that are defined in the standards. Symbols refer to characters generated by a computer, writer, or other devices when receiving a signal that is issued when a key is pressed or a key is already pressed.

The original qwerty layout is the currently accepted standard for keyboard character layout. The standard English-language qwerty keyboard has three rows containing alphabet characters and punctuation marks. The remaining rows contain numbers and a space. The carriage return (return), uppercase (shift), tab (tab) and other command type keys can be located at the ends of each row.

In general, input devices, such as computer keyboards, are arranged with separate rows and columns of keys offset from one another. Pressing and holding the uppercase (shift) key adds alphabet and punctuation characters. Function keys, arrow keys and / or separate

a numeric keypad can be added above or to the side of the specified location. In addition, keyboards from various computer manufacturers may contain additional programmable keys for specifying special commands for the keyboard itself.

In addition to the qwerty layout, other character layouts, such as the Dvorak keyboard, have been developed. It is clear to the skilled person that there can be any arrangement of characters, such as a qwerty arrangement or arrangement of Dvorak or others similar to them. In addition, the present utility model can be used with the arrangement of characters other than standard English characters in keyboards with characters of other alphabets. Thus, it should be clear that the present; useful utility model is not limited to a specific arrangement of characters corresponding to; each key.

There is a device for input with a fixed key, containing many keys for generating input signals corresponding to each letter of the alphabet, in which the keys are located with horizontal and vertical distances between the center lines of the keys, and the horizontal distance between the center lines of the keys is 10.8 - 16.4 mm, the vertical distance between the center lines of the keys is 10.8 -18.0 mm. (patent of the Russian Federation NO 2137609 C1).
